First early potatoes

Im new to this game so please be gentle with me,i was wondering if
it is to late to plant first early potatoes,ive got some off a freind but its been that wet
that ive not had chance to plant,they are charlotte and lady christie variety 

Thanks for that,its been that wet for weeks that ive found myself
way behind

I have had fIrst and seconds chitting since Feb, they had some lovely chits on them, but I was way behind on getting them out and decided to plant them in grow bags, haha I wondered whether I should water them, well they are getting plenty today, hope they dont rot or something.
